I've been running Squeezebox Server on a Sheevaplug since July 2010 with no problems. Now it boots up like always, but after about 10-15 minutes, it unceremoniously goes dark. It has to sit for at least an hour before it can be started again.

I boot from an SD card but I get this behavior with and without the card and whether or not anything is plugged into the ethernet or USB ports.

Thanks for your reply. Both LEDs turn off. It's as though the Plug has been unplugged.

I'm pretty sure it's hardware because I haven't updated any software other than rescanning the music library in Squeezebox Server. However, as mentioned, it still turns off even with the SD card removed.

The power supply is out and I have an old router power supply that is 5V 2.5A. Do I just remove the connector from the router ps and the connector from the plug ps and connect the two red wires to one of the router ps wires and the two black ones to the other one?

By the way I don't see anything or smell anything that looks burnt. But then the ps hasn't failed completely.

Yes, you could connect the red wired to plus and the black wires to black/ground.The power-supply you did remove from your sheeva seems to a the newer improvedversion which shouldnt smell/burn....but your one did fail....the older ones did fail aftera they burn and smell.

I've stripped the wires on the Linksys. Which one is positive? One wire has a ridge running the length of it and the other doesn't. I've searched but can't find a definitive answer to which is positive and which is negative.

downtime,Look carefully in the lower left corner on the label of your power supply and you will see polarity information.That won't help with the identified conductor (ridge), there are times when a meter or continuity tester is required to be sure.On a similar power supply I have, the identified conductor (white stripe) goes to the center contact (+). YMMV

Hopefully, you have not thrown away the Linksys end connector. On the Linksys box, there is a little diagram which will tell you (probably) that the center part of the connector is positive and the outer portion negative. That will lead to two options.

The first is to cut the end connector plug and find which wire is attached to the center.

Or, you could buy a small outlet to match the external power supply plug, drill a hole into the sheeva box and install that outlet, then just solder the old PSU wires to the matching elements of the new outlet. This would avoid the need to cut the Linksys wires.

If you do not have the connector, then your best bet is to check with a cheap multimeter. Normally, the wire with the identifying element (printing, or the raised ridge) is the positive wire. But, one never knows if the kid in China or Malaysia followed the standard. I would not make any connections just because it is supposed to be a certain way.

Thanks radael & two9er. I followed all of your advice. I had kept the Linksys connector and traced which wire was positive. Just to be sure, I borrowed a voltage meter. Unfortunately, it appears the Linksys ps is dead.

I'm going in the next couple of days to find a new one. I'll let you know how it goes.
